I really love Electric Light Orchestra's Eldorado. I think it's really underrated in their discography and jn general. It's the story of an average, lonely guy who finds more comfort in the stories in his dreams than this life. His dreams are exciting, but are far from what I'd call pleasant. He's a traumatized soldier returning from war, a Native American living in the city after his people were driven out and way of life have been demolished, a man who gave his life fighting with Robin Hood, etc etc etc. It kind of speaks to me of deeper trouble in his life and the album ends with him being unable to cope with reality. He jumps to his death, having realized that it's the key to eternal dream. The orchestral arrangements are lovely, the music itself is pretty varied while sticking to the concept, and the vocals are incredible.
